What is the mean, the median, and mode of the set of values: 17, 19, 22, 9, 18, 13, 24, 6, 25?

Josiah Allen

Mean #=17#
Median #=18#
Mode #=#none

The numbers can be sorted first

#6" " "9" " "13" " "17" " "18" " "19" " "22" " "24" " "25#

By inspection we can see the middle number #18#

Median #=18# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Compute for the Mean

Mean#=(6+9+13+17+18+19+22+24+25)/9=153/9=17#

By observation, there is no mode

God bless....I hope the explanation is useful.
